T0 aZZ whom 2'23 may concern:

' Be it known that I, OLINDo VALERI, a citizen of the Kingdom of Italy, and resident of 21 Col-so Oporto, Turin, Italy, have invented certain new and useful Improvements in Means for Fixing Railway-Lines, of which the following is a specification, such as will enable others skilled in the art to which it appertains to make and use the same. 1 i

This invention relates to improvements in means for supporting railway and tramway tracks.

One of the objects of the invention is to provide longitudinal sleepers, and means associated therewith to render the rails of a track effective means for supporting the rails.

According to this invention, longitudinal sleepers are used which are preferably of synclinal form at the bottom and are adapted to rock longitudinally about a transverse axis, the sleepers being arranged on solid foundations in the form of concrete blocks over which the rails are laid, and the several sleepers beneath eachrail being interconnected'one with another.

The invention also comprehends improvements in the details of construction and arrangement of parts to be hereinafter de scribed and particularly pointed out in the claims.

In the accompanying drawings:

Figure 1 illustrates in side elevation a portion of the rail track with the invention applied thereto.

Fig' 2 is a plan view of the same.

Fig. 3 is a transverse section of a track, one of the rails being tilted with respect to the other.

Fig. a shows a detail side elevation of a portion of a sleeper, and a rail supported thereon.

Referring to the drawings, aa indicate the rails supported by a series of longitudinally spaced sleepers 0, of cement or concrete, disposed longitudinally beneath the rails. The sleepers are connected by means of ties b, secured in eyes formed on ends of rods h, embedded in the concrete. The bottom of each sleeper is inclined toward the middle, and at the apex of the inclined bottom surfaces of each sleeper is a transverse insert in, forming a rocking surface which bears upon a metal plate Z, inserted in the top of a concrete foundation block (Z, disposed along the track bed, there being, of course, a block under each sleeper. The rails a, rest on blocks or cushions e, of wood or the like, disposed on the tops of the sleepers 0, for the purpose of doing away with the resonance of the ordinary cement sleepers. Bolts 9, having at their lower ends hooks, extend'each side of the blocks 6, and engage eyes m, projecting from the sleepers. The upper ends of the bolts 9' pass through clamps which engage the rails, and nuts are threaded on the bolts to hold the clamps in position. f indicates tie rods extending across the underside of the track, and mounted on the tie rod are clamps H, which engage the base of each rail, and are held in clamped position by means of nuts 0, threaded on the rod. Depending from the tie rods 7, intermediate the sleepers, are supports 72, which engage the ties b, to assist in holding them in proper position.

As the wheels of a train pass over the rails, they tend to produce an oscillating movement of the sleepers 0 on the foundation blocks (Z, which renders the track resilient, while the interconnection between the sleepers o, and between the other parts of the track, restrict the movement within the desired limits.

As shown in Fig. 1, the construction can be conveniently employed when it is desired to incline a rail used for a curve.

l/Vhat I claim is:

l. The combination of a pair of rails, con

crete blocks arranged lengthwise beneath the rails, the bottom of each block inclining from the opposite ends toward the. middle, a support for the central portion of each block, and means for securing the rails to the blocks.

2. The combination of a pair of rails, blocks of reinforced concrete arranged lengthwise beneath the rails, the bottom of each block being of synclinal form.

3. The combination of a pair of rails, longitudinal sleepers having bottoms of synclinal form, and foundations of concrete on which the sleepers are supported.

4. The-combination of a pair of rails, longitudinal sleepersarranged under the rails, each block having a rocking surface on its under side, foundation blocks for supporting the sleepers, and connections between adjacent sleepers.

5. The combination of a pair of rails, longitudinal sleepers, each sleeper being of synclinal form at the bottom, cushions on the sleepers and on which the rails rest, means -to retain the rails in position on the cushions and sleepers, and blocks supporting the sleepers and forming surfaces on which said sleepers can rock.

6. The combination of a pair of rails, longitudinal sleepers of synclin'al form at their bottoms, connections between adjacent sleepers, means to retain the rails in position on the sleepers, adjustable means for holding the track to gage, and blocks forming rocking surfaces for the sleepers.

T. The combination of a pair of rails, longitudinal sleepers of synclinal form at their bottoms, cushions of wood on the sleepers on which the rails rest, means for retaining the rails in position on the sleepers, said means being anchored to the sleepers, tierods for connecting adjacent sleepers, ad-

justable gage-bars clamped to the rails, connections between the tie-rods and the gagebars, and foundation blocks forming rocking surfaces for the sleepers, one foundation block being provided for each sleeper.

8. In combination, a rail, a series of longitudinally disposed sleepers below the rail, the bottom of each sleeper inclining from opposite ends toward the center, a block supported near each end of the sleeper to support the rail, means for fastening the rail, blocks and sleepers together, means for supporting the sleepers to permit them to rock, and longitudinal connections between the sleepers to hold them in alinement but to permit of slight rocking movement.

In witness whereof I have hereunto set my hand in presence of two witnesses.

OLINDO VALERI.
